Embodiment Construction

[0023]An example of a V-BLAST wireless system is schematically illustrated in FIG. 1, in which a single data stream is divided into multiple substreams for transmission in a rich scattering (multipath) environment. The V-BLAST system treats the multiplicity of scattering paths as separate parallel subchannels, each carrying a substream of data.

[0024]Referring to FIG. 1, the V-BLAST system includes a vector encoder 11 and a V-BLAST signal processor 21 at a receiver 20. The vector encoder 11, for example as part of a fixed host 10 (e.g., a base station or Node B) or a transmitting device, is connected in parallel to M antennas for respectively transmitting a plurality of data substreams a1-a4. The V-BLAST signal processor 21, as part of a subscriber unit, a mobile terminal, a mobile device or a user equipment (UE) 20, for example, (hereinafter, a mobile terminal) is connected in parallel to N antennas, each for receiving the plurality of transmitted data substreams. As shown in the ex...

Abstract

A method of mobile communication including a transmitter having multiple transmitters and a receiver having multiple receivers. The method includes adding a cyclic redundancy check (CRC) code to a data block to be transmitted and spatially segmenting the data block according to a modulation scheme and a coding rate of each respective transmit antenna of the multiple antennas.

Description

CROSS-REFERENCE TO A RELATED APPLICATION[0001]This application claims the benefit of Korean Application(s) No. 10-2003-0031026 filed on May 15, 2003, which is incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to wireless communication systems, and more particularly to a mobile communication system and signal processing method in which an indicator such as a cyclic redundancy check (CRC) code added to a data block is used to determine whether an error in transmission has occurred.[0004]2. Background of the Invention[0005]Multiple-input multiple-output (MIMO) wireless communication systems use multiple-element antenna arrays to increase a user capacity in rich multipath environments by exploiting the spatial properties of the multipath channel. One such system is the vertical BLAST (Bell Laboratories Layered Space-Time) system, which uses a vertically layered space-time architecture as opposed to the diagonally laye...
